患者男性,46岁,工人。心跳,气短,恶心,呕吐二周,于1972年3月21日入院。临床诊断:心肌病。心电图分析:各导联P波消失,可见心房纤颤波(f波),在V_1导联比较清楚,R—R间期绝对不等,说明心律为心房纤颤。肢体导联QRS电压算数和<0.5mV,示低电压,心室率平均80次/分;可见较长而恒定的R—R间期,如:aVF中R_2—R_3间期为1.56秒,V_1中的R_2—R_3间期亦为1.56秒,因此aVF中的R_3和V_1中的R_3均为结性逸搏,提示存在第Ⅱ度房室传导阻滞。额面向量心电轴为-60°,Ⅰ、aVL导联为qRS波,Ⅱ、Ⅲ、aVF为rS型波,
Male patient, 46 years old, worker. Heartbeat, shortness of breath, nausea, vomiting for two weeks, on March 21, 1972 admitted. Clinical diagnosis: cardiomyopathy. ECG analysis: P wave disappeared in each lead, showing atrial fibrillation wave (f wave), V_1 leads more clearly, R-R interval is absolutely not, that the heart rate of atrial fibrillation. Limb lead QRS voltage arithmetic and <0.5mV, showing low voltage, ventricular rate average 80 beats / min; visible long and constant R-R interval, such as: aVF R_2-R_3 interval of 1.56 seconds, V_1 Of the R_2-R_3 interval is also 1.56 seconds, so aVF R_3 and V_1 R_3 are knot Yat, suggesting the existence of the second degree atrioventricular block. Frontal ECG axis is -60 °, Ⅰ, aVL lead is qRS wave, Ⅱ, Ⅲ, aVF is rS type wave,
